CULTIVATOIRI SPECIFICATION fOrming part of Letters Patent No. 284,960,dated September 11, 1883.

Application filed April 13, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we, PHILLIP HIEN and As- MUS H. GRIMM, citizens of theUnited States, residing in Rock Island, Illinois, have invented certainImprovements in Cultivators, of which the following is a specification.

The present improvements relate to the draft apparatus, to the meansemployed for connecting the cultivator-beams to the arched frame, and tothe method of hanging and supporting the bars or runners which are usedwhen the machine is being drawn to and from the field and the beams areelevated, the objects of the improvements being too fully explainedhereinafter to need preliminary description.

In the accompanying drawings, Figure 1, Sheet 1, is a perspective Viewof theimproved cultivator with both beams elevated; Fig. 2, aperspective view of the arched frame detached; Fig. 3, Sheet 2, a sideview of that part of the machine to which our invention relates; Fig. 4,a plan view of the same; and Figs. 5to 12, inelusive, detached views ofparts of the cultivator. The views on Sheet 2 are on a larger scale thanFigs. 1 and 2.

A is the arched frame of the cultivator, and to the lower portion ofthis frame are securely bolted the open side frames, B B, to which arepivoted, in the manner described hereinafter, the cultivator-beams D D,each of the latter being furnishedwithasuitablehandle,asusual. Thearchedframe consists of abar, 5v,with central rib, w, the latter beingdiscontinued some distance from the lower end of each leg of the arch,so as to form seats yfor the frames B. The arch thus made possesses thequalities of lightness and strength.

The wheels F F are indep endent of each other, each wheel being free toturn on a short axle, G, a detached view of which is shown in Fig. 5.This axle has at the inner end a hollow vertical stem, a,which isadapted to eyes I) b-on one of the frames B, and is confined theretovertically by means of a cap, d, which bears upon the upper eye, and issecured in lace by means of a bolt and nut, as shown in Figs. 5 and 9.By this means each axle is pivoted to theframe B, so as to swingthereon.

Each draft-bar J is hooked at the outer end for adaptation to the eye ofthe whiffletree, the inner ends of the draft-bars being fitted to thestems a of the axles, between the eyes I) I). From the outer ends of thedraft-bars to the outer ends of the axles extend rods K, which are bentso as to accommodate the wheels, the rear ends of the rods fitting overthe ends of the axles, as shown in Figs. 1, 3, and 4, and being retainedthereon by suitable pins. By this means draft is applied to the axles.both inside and outside of the wheels; hence there is a more directpull upon the axle than when the draft is applied at one point only, thestrain being thus more evenly distributed, risk of breakage lessened,

and the wheels caused to quickly and accurately follow any change in thedirection of the draft, for as the outer end of the draft-bar is movedto right or left there is a definite swinging movement of the axle and aproper change in the position of the wheel, as will be readilyunderstood on reference to Figs. 1 and 4.

To the front end of each beam D of the cultivator are bolted a pair ofplates, f, the front ends of which arebent so as to embrace a block, 9,openings in the bars f, being adapted for the reception of twocircularhubs, i, on the block,

so that the beam is pivoted to said block. The latter is pivoted to theframe B by means of a vertical bolt, m, so that a universal jointbetween the frames B and beams D is formed. The swinging movement of thebeams on the hubs i of the blocks 9 is limited, however, by transversebolts a, which are adapted to slots a in the block, so that the arch Ais prevented from tipping forward or backward beyond a certain extent.-To facilitate the manufacture of the block 9 it 'is made in halves, asshown in Figs. 4, 5, 6, 7, and 8.

To a lug, p, 011 the rear end of eachdraft bar J is hung an arm, M, alug, g, on said arm projecting beneath the'hollow stem a of the axle G,and having aprojection, 8, adapted to the central-opening of said stem,so that while the arm M is free to swing with the draft-bar and axle itcannot swing upward. (See Fig. 9.)

To the rear end of each arm M is pivoted a runner, N these runnersbearing upon the ground and supporting the frame when the cultivator isbeing drawn to and from the field, as shown in Fig. 1, the beams D inthis case being elevated and supported by arms P, projecting rearwardlyfrom the arch. 7 Each runner consists of a lever the short arm of whichLOO projects above the arm M, and when the 'runneris in use bears upon adog, w, Fig. 10, this dog being hung within a slot in the arm M, andhaving shoulders bearing on the top of said arm, so that when the partsare in the positions shown in Figs. 3 and eithe runner is locked to thearm, so far as upward movement of its outer end is concerned. When it isnot desired to use the runner, however, the latter may be moved so as torelease the dog and permit it to be thrown up, as shown in Fig. 11, andthe arm can then be thrown upward and forward to the position shown inFig. 12, the dog being allowed to drop, so as to afford a support forthe runner. When the runner is thrown down again, the short arm of thesame will strike and lift the dog, which will then fall into placebeneath said arm, so as to automatically lock the runner in position.

We claim as our invention-- 1. The combination of the frame B, havingeyes I) b, the axle G, having a stem, at, adapted to said eyes, and thecap- (1, bearing upon the upper eye, I), and bolted to the upper end ofthe stem a, as set forth.

2. The combination of the frame 13, having eyes 11 b, the axle G,havinga stem, a, adapted thereto, the draft-bar J, hung to the said stema, and the rod K, connected to the draft-bar and to the outer end of theaxle, as set forth.

3. The combination of the frame B, theaxle G, having a stem, a, adaptedto eyes on the frame, the draft-bar J, and the runner-carryin g arm M,hungtothe draft-bar, and havinga projection, 8, adapted to a centralopening in the stem a, as set forth.

p 4. The combination of the frames B, th blocks 9, pivoted thereto, andthe beams D, the end plates, f, of which are pivoted to hubs i on saidblocks g, as set forth.

5. The combination of the framesB, the pivoted blocks having slots n,and the beams D, having end plates, f, pivoted to the blocks 9, andhaving bolts n, adapted to the slots n,.as set forth.

6. The combination of the frames B, the bolts m, the blocks 9, made inhalves, and the beams D,with plates f, confining said halves, as setforth. I

7.. The combination of the arms M, the pivoted runners N, and thelocking-dogs w, asset forth. 7

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
